HENRY COOK, OF WELLSTON, OHIO.

SAFETY BRAKE-RIGGING.

To all whom it may concern:

Be it known that I, HENRY Coon, a citizen of the United States, residing at Wellston, in the county of Jackson and State of Ohio, have invented a new and useful Safety Brake-Rigging, of which the following is a specification.

This invention relates to safety brake rigging for railway cars, particularly freight cars.

It is the object of the present invention to provide a brake rigging so constructed and attached to the car body, that the several parts cannot become detached, or that the brake beam cannot be released, notwithstanding the various conditions to which the rigging is subjected.

It is a further object of the present invention to provide a rigging of the character indicated which shall be simple, durable, substantial and inexpensive in construction, as well as convenient, serviceable and efficient in use.

The present invention also contemplatesa brake rigging which is applicable to various cars embodying different sizes of sills, hanger blocks or the like.

With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter de-' the hanger. Fig. 4 is a plan view of a detail, and Fig. 5 is a plan view of another detail. Fig. 6 is a fragmental perspective of a modified form.

Referring specifically to the drawings, a portion of the car body has been designated by the numeral 6, the same including the sill, or hanger block 7 on the bottom thereof and extending transversely of the car body, as customary.

Specification of Letters Patent.

Application filed December 28, 1912.

A hanger 8 is attached to Patented Aug. 55,1913. Serial No. 739,144.

each end of the sill 7 adjacent the corresponding car wheel, only one of the said hangers being illustrated, for the reason that a double use thereof is clearly apparent. This hanger 8 has the brake head 9 attached on the lower end thereof, the said head being attached to the corresponding end of the brake beam 10, and the brake 11 being attached to the head 9 in the usual fashion.

In carrying out the present invention, the hanger 8 is constructed from a suitable metal rod, bentinto a hook 13 at its upper end and into a plurality or a series of square loops 12 immediately below the hook 13. The hook 13 of the hanger is engaged to the hooked end 1 1 of the usual hanger bolt 15 which passes through the sill 7. The lower end of the hanger 8 is bent into an eye or loop 8 through which the intermediate portion of a clevis 17 passes loosely, and a pin 18 is passed through the terminal eyes of the clevis and through the usual passage provided through the brake head 9 in order to attach the head to the hanger. The loop of a cotter pin 19 slidably engages one arm of the clevis l7 and when slid downwardly or outwardly is adapted to pass through an opening provided in the pin 18, so as to lock the pin 18 in position. The loop 8" terminates in a hook 20, and a latch 21 cooperating with the said hook is se cured rigidly to the clevis 1.7 adjacent the hanger, the free end of the latch normally engaging the tip of the hook so as to close the hook. A pair of collars 22 are preferably secured on the intermediate portion of the clevis 17 at the sides of the loop or eye 8 in order to retain the clevis and hanger in proper relation, the brake head 9 also being provided with an outwardly projecting ear 23 at its upper end provided with an aperture through which the hook 20 is engaged.

The clevis 17 passing loosely through the eye 8 is permitted to swing so as to allow the brake shoe 11 to swing to and from the car wheel as the beam 10 is actuated, either by a hand brake or by the usual air cylinder connected to the train line. The ends of the clevis 17 being pivoted to the sides of the brake head 9 and the hook 20 which is rigid with the hanger 8 being connected to the ear 23 permit the latch 21 to be swung away from the hook 20 when the brake head 9 is swung outwardly or away from the car wheel suificiently. Ordinarily the brake head 9 cannot be disengaged from the hanger and to disengage same, the pin 18 nirst iirst be removed by disengaging the cotter pin 19 therefrom and withdrawing the pin 18, and then swinging the brake head 9 outwardly so that the latch 21 frees the hook 20 and then swinging the head 9 so as to disengage the hook 20. It. will thus appear that the brake head 9 in use cannot aceiden tally become separated from. the hanger and the loss of the brake beam is therefore eliminated, that is, from the hangers at the two sides of the car body.

The plate 2 1 is screw-threaded onto the end of the bolt 15 opposite the hook 141 to which the upper end of the hanger is engaged, the said plate 24E having a screwt-hrnided aperture 25 into which the end of the bolt 15 is engaged and the said plate also having a series of square openings 26 complementing the loops 12 of the hanger. A cruciform member 27 is arranged below the sill 7 and has one of its arms passing through one of the loops 12 and the opposite arm passing through the corresponding opening 26, the arms of the said cruciform member 27 being perforated for the reception of cotter or locking pins 28 for retaining the h anger and plate 24 in position. One pair of the arms of the cruciform member 27 are longer than the other pair, the pair of arms which is idle lying longitudinally below the sill. The hanger 8 may thus be attached to sills, or hanger blocks of various sizes, for the reason that the member 27 may have either pair of its arms engaged through corresponding loops and openings of the hanger and plate, respectively, the locking pins 28 also being engageable at various distances along the lengths of the arms of the cruciform member 27.

In the variation illustrated in Fig. 6, a supplemental or auxiliary clevis 17 is employed in conjunction with the clevis 17 in order to accommodate certain brake heads, which do not have the apertured ears 23 s above described, but on the other hand are provided with a pair of openings therethrough. This auxiliary clevis 17 is provided with an eye 30 at its intermediate portion enga the hook 20 and the arms of the clevis are provided with loops 81 adapted to engage the pin 18, while a pin 18 is passed through the eyes of the clevis 17'. A cotter pin 19 is preferably slidable on one arm of the clevis 17 to engage the end of the pin 18. When the clevis 17' is amei'nbled with the clevis 17, the device is applicable to brake heads having a pair of openings therethrough, the pins 18 and 18 being adapted to pass through the openings in the brake heads. It will be manifest, also, that should either of the pins 18 or 18 become broken or lost, there will be no liability of the brake head becoming lost. It will. thus be noted that the auxiliary clevis may be employed in connection with the primary clevis, or may be omitted, as necessary or essential.

From the foregoing, taken in connection with the drawings, it will be apparent that the present rigging cannot become detached, or the several parts cannot become separated, so that the loss of the brake beam and brake shoes together with accompanying parts, is eliminated.

Having thus described the invention, what is claimed as new is 1. In a brake rigging, a hanger, a clevis carried thereby, and a cooperating hook and latch carried by the clevis and hanger.

2. In a brake rigging, a hanger, and pri mary and secondary brake head supporting means carried thereby.
